UNITED STATES PATENT OFFICE-.-

Ive. 840,519.

.Be it knownthat I, READ RUssEIJL, of Warren, county of-Jo Daviess, State of Illii nois, have invented certain new and useful than the ordinary truck.

' truck Im rovements in Car-Trucks, 'of which the fol owing isa s ecification.

The ob'ect o my invention is to provide a truckwhich will run easier or with less power A further object is to provide a truck which can be run round curves with less friction between the wheels and rails.

' A furtherobject is to pro, 'de a car-truck having wheels which have no tendency to separate or spread the rails while running overthem. The invention consists generally in a carrovided with wheels having axles journa ed on both sides of the wheel on each side of the truck, the axle of each wheel being movable independently of the correspondin%axle onthe opposite side.

'urther, the invention consists in roviding a truck with wheels having fiat caring surfaces or treads to rest upon the rails. Further, the invention consists in various constructions and combinations, all ashereinafter described, and particularly pointed out in the claims.

.In .the accom anying drawings forming part of this specification, Figure 1 is a plan view of a truck embodying my invention.

' Fig. 2 is a side elevation of the same.

Fig. 3 is a transverse vertical section, and Fig. 4 is a plan view, of one of the wheels and Its axle v removed from the truck. a

In the drawings, 2 and 3 represent the side I rails of thejtruck arranged in pairs upon each side with a sufficient "s acebetween-them to accommodatethe whee s. Cross-bars 4 connect thefrails at the ends of the truck, suitable angle-brackets 5 being provided at the intersection of the'rails and cross-bars, securing'them together and-bracing the truck se-' cured together at themiddle of the truck be- 'neath the bolster 7 which; is provided with suitable springs, such as 8, and the usualking-bolt 9.

' The. whe

axles 11, journaled on eachside of the .wheels The wheels '10 are provided short in boxes" 12, which are bolted to. the rails 2 7 and 3 and depend below the same, as shown in Fig. 3. Each axle is thus inde endent of all the others and with its whee can turn without affecting the otherwheels and axles.

When, therefore, the truck is rounding a curve in the track the wheels on the outside can travelfasterthan those on the-inside without increasing the friction between the wheels and --Ithe rails. Furthermore, eadh wheel having "bearings on each side of the truck will run more uniformly and the wear in the bearings willbe less 'erceptible than wherea single axle exten ing across ther truck is provided for eachv pair of wheels. s are all provided with flat bearing surfaces or treads 13, whichjrest squarely upon the fiat tops 14 of the rails 15 and have no tendency to spread or separate the rails while r over them, and there will be less friction between this form of wheel and the rails than between the wheels'and rails as usually made. The truck will therefore run easier and there will be less wear on both the wheels and the rails.

I claim as my invention- 1. A car-truck comprising channel-bar- 3 iron side rails 2 and 3, arr'angedin airs on eachside of the truck'with a space etw'een the ralls of each pair, cross-bars 4 also of channel bar-iron, connecting the ends of said side rails, brackets 5 provided in the angle formed'by'said cross-bars and the inner rails of said .pairsand securing them .tizgether,

sbol

ed to the inner side rails near said brackets tween said rails. an secured together near the middle of the'truck, a bolster 7 rovided above said truss-rods near the mid e of the same and wheels arranged in the spaces be-' '5 and extending len thwise ofthetruck-between the rails of each pair and having axles journaled in boxes secured to said side rails,

whereby independent. movement of said loo wheels is permitted, to facihtate the passing of the truck around a curve.

spaces between the'rails' o bars c'onnecting said side rails, truss-rods... I bolted to the inner rail of each pairand secured together near the middle of the truck, a bolster having springs located above said rio 5 journaled in said boxes and movable indeseams 1 -rods and centrally on the truck, boxes In witness whereof I have hereunto set my bolged tn the mlifr faces off the mgtefl rails of hand this 31st day of August, 1905. eac air an t e. inner aces. 0 t e inner Y rails 3f said pairs and Wheels having axles READ RUSSELL Witnesses:
